powderblue Posted June 18, 2003 Share Posted June 18, 2003 I have two 25 watt bulbs in my 10 gallon nano-reef. I cant seem to keep the tempature below 90 degrees in there. (Dont worry I dont have any fish or invertabrates in there!) Does anyone have advice to help me keep the tempature 75-80 degrees? thanks in advance. P.S. whats does pc mean (IE: "1 25 watt pc in my nano" thanks:) Link to comment
jprime Posted June 18, 2003 Share Posted June 18, 2003 1. Try getting more air movement around the lights (open the hood or add a fan across the lights). 2. Try blowing a fan across the water for evaportative cooling (works great on my 10g with 110w of lighting). 3. Switch to closed loop, external pump for water movement. Powerheads put out some heat, all of which is transfered to your water! Good luck! -Jon Link to comment
SeaMountain Posted June 18, 2003 Share Posted June 18, 2003 PC = Power Compact. Referring to the type of lighting you are using. Link to comment
powderblue Posted June 18, 2003 Author Share Posted June 18, 2003 where can I get a small enough fan to blow across my lights and what is the general price in the US? Link to comment
jprime Posted June 18, 2003 Share Posted June 18, 2003 You can goto an electronics store like RadioS******. They have AC or DC/transformer fans. About $20-$30. I got a small 2 speed AC fan for $4.50 at WallM****** -Jon Link to comment
powderblue Posted June 18, 2003 Author Share Posted June 18, 2003 will it fit in my small 20 inch 10 gallon hood? IT meaning the 4.50 2 speed ac fan Link to comment
jprime Posted June 18, 2003 Share Posted June 18, 2003 Probably not. It's 7"W x 8.5"H. My entire setup is enclosed in a stand (covers the top and sides of the tank also). I use one of those fans to evacuate the air from the stand (near the lights). If the hood is DIY, you may be able to put the fan on top, sucking out like I did. You can get very small ones the the electronic store but it's gona cost you. -Jon Link to comment

powderblue Posted June 18, 2003 Author Share Posted June 18, 2003 what do you mean "what sort" ( I'm REAL slow!) Link to comment
jojopus Posted June 18, 2003 Share Posted June 18, 2003 You say you dont know what PC lights are so Im wondering what kind of lights you are using and what color temperature they are. Are they just incandescent lights.... a picture would probably clear it up. BTW. Lighting in a reef tank, as you're quickly learning, is somewhat of a complex issue. Just give it some time, do some (wait...not some, ALOT of) research, and youll know everything you need to. Link to comment
powderblue Posted June 19, 2003 Author Share Posted June 19, 2003 Yes thats it incandescent lights are what they are, I have 2 25 watt incandescent bulbs. On the package it said "for use in home appliances and aquariums" Link to comment
powderblue Posted June 20, 2003 Author Share Posted June 20, 2003 Going to try and get some brighter lights that are NOT incandescent because of the heat they give off. Link to comment
cuteios Posted June 20, 2003 Share Posted June 20, 2003 powder: you should really switch to different bulbs...the heat isn't the only problem the light color is a major thing to consider too. I thought I had it rough I could only find 6500K bulbs. Consider PC too...it shouldn't be too hard to retrofit your hood for those bulbs...check out the DIY section. The PCs don't give out half the heat the incandescent bulbs produce. Link to comment
Bruce Dunphy Posted June 20, 2003 Share Posted June 20, 2003 A rule of thumb on the fan--always blow INTO the tank canopy (with someplace for the air to escape, of course). If you suck the air out you pull humid air through the fan, significantly reducing the life of the fan. Link to comment
jprime Posted June 20, 2003 Share Posted June 20, 2003 Yea. My tank is in an enclosed stand (only the front glass is visible). If I push air in (from the top where its hot) the hot air will run through all parts of the enclosure before escaping. I decided to suck out instead. My fan was $4.50. At that price I can easily replace it at the first sign of corrosion. -Jon Link to comment
powderblue Posted June 20, 2003 Author Share Posted June 20, 2003 thanks. I will check out the diy section! Link to comment
powderblue Posted June 26, 2003 Author Share Posted June 26, 2003 I fixed the problem by getting a fan and blowing it across the hood! Link to comment
